The Native Americans were grouped into tribes or nations usually based on the area they lived in and their culture such as their religion, customs, and language. Sometimes smaller tribes were part of a bigger tribe or nation. As best as historians can tell, these tribes were fairly peaceful prior to the arrival of Columbus and the Europeans.
There were hundreds of tribes throughout the United States when Columbus first arrived. Many of them are well known such as the Cherokee, Apache, and the Navajo.
Young children and babies spent all of their time close to their mother. The mother would go about her daily work and chores carrying the baby on her back in a cradleboard. The mother often nursed the young child until it was two or three years old.
